Re: Pierogi help
Bells, probably the most common filling is based on mashed potatoes, but I've never made those.
My Polish family has made two kinds all my life: one kind is stuffed with Farmer's cheese (like ricotta, only much drier), and tiny-diced salt pork which is fried till golden. The other kind is made with drained and rinsed saurkraut, sauteed onions, and rehydrated dried mushrooms.
The dough is simply King Arthur's flour (very important - that brand works best), a little warm water and a small chunk of chilled butter.
The technique of dough-making, resting, rolling out, cutting out, filling, pinching shut, boiling, and draining is a process that requires time. My family always made the fillings one day, then did all the rest the next day.
Let me know how much detail you would like and I'll help if I can (though I am going out most of the day today).
This is time-consuming, but storebought pierogi can't compare to homemade!
Photos below are of pierogi draining and then after being reheated in a frying pan with a little butter, sprinkled with diced fried-out salt pork, served with borscht.
